During the past two weeks, I've been creating ambient occlusion bakes for all current OpenArena characters.I rendered the textures with padding, so you won't get any black seams. I also included a mask in the alpha channel that has the UV islands without any padding.

The Quake 3 engine does not support ambient occlusion to be added as a shader.

These are simply meant as painting base for new skins. Instead of starting with a blank wireframe texture, you can now start with these. That way, there's already some basic shading in place, and then you can just add your own colors, details and more shading as needed.

You can also set it as a multiply layer to a skin, to add more depth to the shading. So if you've made a skin, and you think the shading could use a little more oomph, try adding these.
